This document is mainly geared toward Linux 2.4. It covers
secondarily earlier Linux. It covers newer Linux only partially, but
the author's goal to cover it completely in a future release. See
in particular Section 12.
The
subject changed quite a bit over the course of Linux 2.5 releases, and
this document ignores 2.5, since the 2.5 releases were not considered
production releases. Instead, the document treats all the changes in
2.5 releases as if they were new with Linux 2.6.
